48l/h does seem low for 2 blocks.

Can you post a screen shot of your pumps tab in aquasuite? (example below)
48lph.jpg

I am not sure if the Minimum/Maximum power settings on your pump are used with the automatic control option, but having it at 100% for minimum and maximum could force the pump to 100%... which may have been your intent.
That said, the issue remains as to your relatively low flow rate.

Perhaps if you describe your system a bit... we know you have a CPU & GPU water block, but what size is your tubing, and how many 90° fittings, etc.,
Also, is there a way debris/dirt may have entered your loop during assembly causing blockage.

As a test, you could set your "Minimum pump value" to 30%, leave the "Maximum pump value" at 100%, then use the "Manual preset" option to move the pump power up/down and see what happens to the flow rate.

Lastly, the real pros/reps are on holiday at this time, and hopefully they will be able to help you come Monday when they may be back.

How are your GPU & CPU temperatures?

Hi Bullrott,

Did you try running with no blocks at all, or just one block installed, just to see if they are the problem? For instance EKWB CPU waterblocks are unidirectional. I don't know how much of a difference it makes if you get the direction wrong but it's something to check.

Not sure how it goes with aquaduct, but is your flow sensor configured properly, by this I mean the impulse/liter value?

Kind regards,
Boris.

Hi,

I try running with on block, same flow, with no block flow reach 56l/h

"Not sure how it goes with aquaduct, but is your flow sensor configured properly, by this I mean the impulse/liter value?" =) How you do that?

If I remember correctly, the Aquaduct product comes preconfigured correctly as the pump and flow meter are hard-wired without options.

Little up since now pro must be back from holiday

I change the tube for some 10/16mm and now I have 70l/h

Nice!

Can somebody tell me how many flow is needed is an loop/ system?
I have ten 90 degree angel fittings an two 360 radiators a CPU and GPU block Flow meter .
The DCC PWM pump gives me at 37 % pwm a flow of 80 L/H and at 100 % 220 L/H

An efficient flow needs to be run within the range of 1.0-1.5 GPM. Just have to convert that to L/H and you should be good to go.
